My corals both SPS (e.g., spongodes montiopora,montiporal-capricornis orange) and zoas are growing very well, but they just lack color. Is lacking color generally a result of too much/not enough light.
I have been having some issues with calcium not being high enough. I'm relatively new to this and just discovered that I needed to check magnesium as well as all of the other things. Yesterday I added Mg for the first time, check it today, and it was still low. So I added more today.
My other parameters are great.
